Global monthly mean atmospheric carbon dioxide, 1979-2022. The global surface average for CO2 rose by 2.13 parts per million (ppm) to 417.06 ppm, roughly the same rate observed during the last decade. Atmospheric CO2 is now 50% higher than pre-industrial levels. 2022 was the 11th consecutive year CO2 increased by more than 2 ppm, the highest sustained rate of CO2 increases in the 65 years since monitoring began. Prior to 2013, three consecutive years of CO2 growth of 2 ppm or more had never been recorded. The Global Monitoring Division of NOAA/Earth System Research Laboratory has measured carbon dioxide and other greenhouse gases for several decades at a globally distributed network of air sampling sites. This graph shows monthly mean abundance of carbon dioxide globally averaged over marine surface sites. Graphic: NOAA Global Monitoring Laboratory

Greenhouse gases continued to increase rapidly in 2022 – Carbon dioxide, methane, and nitrous oxide rise further into uncharted levels – “Greenhouse gas emissions continue to rise at an alarming pace and will persist in the atmosphere for thousands of years”

5 April 2023 (NOAA) – Levels of carbon dioxide (CO2), methane and nitrous oxide, the three greenhouse gases emitted by human activity that are the most significant contributors to climate change, continued their historically high rates of growth in the atmosphere during 2022, according to NOAA scientists. The global surface average for CO2 rose by 2.13 […]

Gulf of Mexico oil worse for climate than thought, study – “Expanding production in shallow waters, the way it’s been done historically, would have disproportionately high climate impacts”

By Drew Costley 3 April 2023 (AP) – Offshore oil and gas operations in the Gulf of Mexico are releasing far more climate-changing methane than official estimates show, according to a new study published Monday. Using data collected from aircraft in part, climate scientists found the additional methane coming from oil and gas platforms in the Gulf […]

Record-breaking algae bloom takes aim at Florida beaches – “This year could be the biggest year yet”

By Dinah Voyles Pulver 14 March 2023 (USA TODAY) – Beachgoers in Florida and the Caribbean could be greeted by heavy blankets of smelly seaweed in the weeks ahead as a 5,000-mile swath of sargassum drifts westward and piles onto white sandy beaches. Sargassum, a naturally occurring type of macroalgae, has grown at an alarming rate this winter. The […]

Bushfires could kill almost 2500 Australians by 2030 – “This is not the first report saying this sort of thing, but each of the previous ones have to some extent been ignored by government”

By Lachlan Abbott 2 January 2023 (The Sydney Morning Herald) – Increasingly frequent and severe bushfires linked to climate change could kill nearly 2500 Australians and cost the economy billions of dollars by the end of the decade, according to new research. Modelling from Monash University’s Centre for Medicine Use and Safety has estimated 2418 […]

A toxic stew on cape cod: Human waste and warming water

By Christopher Flavelle 1 January 2023 MASHPEE, Massachusetts (The New York Times) – Ashley K. Fisher walked to the edge of the boat, pulled on a pair of thick black waders, and jumped into the river to search for the dead. She soon found them: the encrusted remains of ribbed mussels, choked in gray-black goo […]

Big oil is behind conspiracy to deceive public, first climate racketeering lawsuit says – “What’s different about this case is that we have their enterprise in writing: the decision by rival companies, their front groups, scientists, and associations to act together to change public opinion”

By Nina Lakhani 20 December 2022 (The Guardian) – The same racketeering legislation used to bring down mob bosses, motorcycle gangs, football executives and international fraudsters is to be tested against oil and coal companies who are accused of conspiring to deceive the public over the climate crisis. In an ambitious move, an attempt will […]

Business is using COP15 to show it’s serious about saving nature, but environmentalists aren’t so sure – “If you come here and your objectives actually are against the objectives of the convention, then we have a problem”

By Marisa Coulton 17 December 2022 (Financial Post) – The UN biodiversity conference in Montreal might go down in history as the moment that business engaged in the fight to preserve nature, but the presence of a thousand corporate representatives is making some the environmentalists who have been attending these meetings for years uneasy. Some […]

Number of Western Monarch butterflies (left) and butterfly surveys (right), 1997-2021. In the western United States, the number of individual butterflies has been steadily decreasing over the past four decades, at a rate of around 1.6% every year, according to a March 2021 study in the journal Science. The iconic Monarch butterfly is one of the species in trouble. Warmer autumn temperatures, an effect of climate change, may be interfering with the butterflies’ hibernation-like period known as diapause. So rather than slowing down ahead of winter, the insects are staying awake longer, expending more energy, and eventually starving to death. In July 2022, the migratory monarch was added to the IUCN’s global endangered species list. Graphic: Catherine Tai / Reuters

Monbiot: The US is a rogue state leading the world toward ecological collapse – “It’s a cliff edge”

By George Monbiot 9 December 2022 (The Guardian) – There are two extraordinary facts about the convention on biological diversity, whose members are meeting in Montreal now to discuss the global ecological crisis. The first is that, of the world’s 198 states, 196 are party to it. The second is the identity of those that aren’t. Take a […]
